The man who died while playing a “punching game” with a friend in a Gaslamp Quarter sports bar was identified by the Medical Examiner’s Office as Corey Poole.

The 27-year-old and a friend were drinking with a group at Jolt ‘n Joe’s on Fourth Avenue when they began consensually taking turns punching each other in the chest just before 1 a.m.

After getting punched several times, one of the punches dropped Poole to the ground.

“After receiving several punches to the chest, the decedent was struck and immediately collapsed and became unresponsive,”' the Medical Examiner's Office said.

Someone called 911 and several bar patrons began giving Poole CPR. San Diego firefighters and paramedics took over when they arrived, and Poole was taken to the hospital.

He died less than an hour later.

The friend Poole had been punching stayed at the location but was later taken to a hospital for treatment of unspecified injuries. He wasn’t arrested, and it’s unclear if he will face charges.

As of Tuesday, the Medical Examiner's Office had not yet determined the cause of death and said the manner of death -- whether an accident, a homicide or something else -- is pending based on the police investigation.
